This guideline provides an assessment of, and presents the evidence base for, the efficacy of non-pharmaceutical therapies, encompassing psychological therapies, structured exercise and lifestyle interventions, and a range of alternative and complementary treatments, many of which are not routinely available within the NHS.

Register of InterestA register of interest is not available for this guideline. In line with the SIGN Document Retention Schedule (24/07/2010), after publication of this guideline, hard copies of declarations of interest were held at the SIGN Executive offices for one year. The declarations of interest were then archived for a further three years before being destroyed along with other guideline related documents. This schedule has now been revised.
